I was on Prolia for 2 years without any side affects. Unfortunately, even while under treatment, I recently had 2 pathologic fractures. So, this week I started Tymlos. I’ve spoken to a rheumatologist who was involved with the drug manufacturer and he told me that no humans developed bone cancer. Unfortunately, most treatments come with potential side effects so it is important to consider all factors. At 71 years old I don’t want to live with the increased chance of more fractures due to severe osteoporosis.
